Product Description

Product Description

 

Introduction

15-7 Mo (UNS S15700) is a semi-austenitic precipitation-hardening stainless steel that provides high strength and hardness, good corrosion resistance, and minimum distortion on heat treatment. It is easily formed in the annealed condition and develops an effective balance of properties by simple heat treatments. For application requiring exceptionally high strength, cold-reduced 15-7 Mo Stainless Steel in Condition CH 900 is particularly useful for applications permitting limited ductility and workability. This alloy is particularly beneficial for a wide range of applications that include retaining rings, springs, diaphragms, aircraft bulkheads, welded and brazed honey comb paneling and other aircraft components requiring high strength at elevated temperatures.

Precipitation Hardening Stainless Steel PH15-7MO Applications

▪ Paneling and springs
▪ Diaphragms
▪ Retaining rings
▪ Welded and brazed honeycomb paneling
▪ Aircraft components bulkheads

Formability
The material in Condition A can be formed comparably to Type 301. It work hardens rapidly and may require intermediate annealing in deep drawing or in forming intricate parts. Springback is similar to that of Type 301. This alloy is extremely hard and strong in Condition C, so fabrication techniques for such material must be used.

Weldability

The precipitation hardening class of stainless steel is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to achieve optimum mechanical properties by considering the best heat-treated conditions in which to weld, and which heat treatments should follow welding. This particular alloy is generally considered to have poorer weldability compared to the most common alloy of this stainless class, 17-4 PH Stainless Steel. A major difference is the high Al content of this alloy, which degrades penetration and enhances weld slag formation during arc welding. Also, the austenite conditioning and precipitation hardening heat treatments are both required after welding to achieve high strength levels. When a weld filler is needed, W P 15-7 Mo or W 17-7 PH is most often specified.
